Dense spherical assemblies of BaCrO4 nanocrystallites of very uniform size (similar to50 nm) were obtained within the two different host matrices. The spherical assemblies were composed of smaller (ca. 5-10 nm size) BaCrO4 crystals indicating that efficient size control over crystal size may be exercised by the matrix. Contact angle measurements of the BaCrO4-StA and BaCrO4-sodium bis-2-ethylhexyl-sulfosuccinate films indicated that they were hydrophobic, thus pointing to the possible role of hydrophobic interaction between the StA and sodium bis-2-ethylhexyl-sulfosuccinate monolayer-covered BaCrO4 crystals in the assembly process.</p>1 aRautaray, D.1 aSinha, K.1 aSainkar, S., R.1 aPasricha, R.1 aPavaskar, N., R.1 aSastry, M.  uhttps://library.ncl.res.in/content/formation-bacro4-nano-crystallites-within-thermally-evaporated-sodium-bis-2-ethylhexyl-0
